  • Different vape styles include Mouth to Lung (MTL), Direct to Lung (DTL), and Restricted Direct to Lung (RDL).
  • Vape devices are made up of an atomizer (usually made up of a coil and wick), a battery, a charge connector (except in some disposables), and e-liquid.
  • Different types of e-liquids include freebase and nic salt. E-liquids also have different VG to PG ratios, which can affect cloud production and other factors.
  • Different types of vape devices include vape pens, pod systems, box mods, and disposables.
  • U Vape carries a wide variety of different vape devices, e-liquids, and other accessories.

So, you’ve decided to pick up vaping and you’re looking for advice on where to start. Vape culture has a ton of different terms and technologies to understand, and some people find it a little confusing at first.

But don’t worry—once you’re familiar with the lingo and know the right questions to ask when picking out products, you’ll be hitting it out of the park in no time (or hitting it in the park, more likely).

At U Vape, we sell tons of a high-quality vaping products, and we’re always happy to share info on how to use them. Below, you’ll find our guide to getting started with vaping—from a breakdown of different vaping styles to a description of common systems and suggested products for beginners.

Different Vaping Styles Explained

Different devices are intended for different vaping styles—so you’ll want to figure out yours before you buy a vape. Here’s a quick breakdown:

Mouth-to-Lung (MTL) Vaping

MTL vaping involves drawing vapour into the mouth first and then inhaling it into the lungs—similar to how you might smoke a traditional cigarette.


  • Tight draw, similar to a cigarette.
  • Often best for higher nicotine e-liquids.
  • Produces less vapour than other styles.
  • A natural choice if you’ve just moved from smoking to vaping.

Direct-to-Lung (DTL) Vaping

DTL vaping involves taking a deep draw and inhaling vapour directly into the lungs.


  • Airier draw with less resistance.
  • Often used with lower nicotine e-liquids and higher VG ratios.
  • Produces more vapour and requires more power.
  • Often preferred by more experienced vape users.

Restricted Direct-to-Lung (RDL)

RDL vaping is a hybrid style that offers a balance between MTL and DTL. It involves a slightly restricted inhale directly into the lungs.


  • Draw is less tight than MTL but more restricted than DTL.
  • Works best with medium nicotine e-liquids and balanced VG/PG ratios.
  • Provides a satisfying throat hit with moderate cloud production.
  • A great choice if you want more flavour than MTL but find DTL too intense.

Anatomy of a Vape System

There are several different types of vape devices (we’ll get to that soon)—but they all have a few common parts. Here are the essentials:


The part of your device that transforms the e-liquid into vapour so you can inhale it through the mouthpiece. Usually, this is a compartment that houses a coil wrapped around a wick.


Coils are made from metal and heated by a charge from the battery in the device. When heated, the coil causes the e-liquid saturating the wick to evaporate, turning it from liquid into vapour. Find replacement coils for your device here.


Wicks are normally made from cotton. They draw e-liquid from the cartridge in your device so it can be heated by the coils and vapourized.


Your vape’s battery sends current through the coil to heat it up and vapourize the e-liquid, saturating the wick.

Charge Connector

A charge connector is built into the bottom of most vape devices so that the battery can be replenished. Most newer vape devices charge via USB-C fast charging ports and cables.


Finally, all vape devices use e-liquid, which is like the “fuel” for your device. E-liquid comes in a wide variety of different flavours—from fruits to various tobaccos and cool menthol varieties.

Different Types of E-Liquids

E-liquids, also known as vape juice, come in various types and formulations to suit different vaping preferences and devices. The two main categories of e-liquids are freebase nicotine e-liquids and nicotine salt (nic salt) e-liquids.

Freebase Nicotine E-Liquids

The most common type of e-liquid, containing pure nicotine in its freebase form.


  • Available in a wide range of nicotine strengths, typically from 0mg to 12mg.
  • Provides a stronger throat hit, especially at higher nicotine levels.
  • Suitable for both MTL and DTL vaping, depending on the device and coil resistance.
  • Works well with box mods and higher-wattage devices.
  • Best for users who want a more pronounced throat hit and traditional experience.

Nicotine Salt (Nic Salt) E-Liquids

E-liquids that use nicotine salts (a form of nicotine found in tobacco leaves) combined with benzoic or citric acid.


  • Smoother throat hit even at higher nicotine strengths, typically ranging from 12mg to 20mg (we also offer Bold 50, which mimics the throat hit of higher concentrations while staying at 20mg/ml).
  • Nicotine absorbs faster into the bloodstream, providing more immediate satisfaction.
  • Best used with lower-wattage, high-resistance devices like pod systems.
  • Ideal for transitioning smokers and those who need higher nicotine levels without the harsh throat hit.

VG vs. PG in E-Liquid

Propylene glycol (PG) and vegetable glycerin (VG) are the two main ingredients in e-liquid, each contributing unique properties.

  • PG is thinner and provides a stronger throat hit, carrying flavours well but producing less vapour.
  • VG is thicker, offering a smoother inhale and creating denser vapor clouds, though it slightly mutes the flavour.

Typically, higher PG ratios enhance throat hit and flavour intensity, while higher VG ratios increase vapour production and provide a smoother draw.

Different Types of Vape Devices

Now that you have a general idea of how vaping works, it’s time to look at some different types of vape devices. Here are some of the most popular types:

STLTH Type C vape pen

Frequently Asked Questions

What's the difference between MTL and DTL vaping?

MTL vaping is generally considered to be closer to the experience of smoking traditional tobacco products, owing to the reduced airflow, while DTL offers direct inhales with larger vapor clouds and more intense flavours.

What VG/PG ratio should I choose for my e-liquid?

Generally, you’ll want to aim for higher VG levels when using a DTL vape style—which means lower resistance and higher power.

How are vape pens different from pod systems?

Vape pens have a built-in compartment for e-liquid and a replaceable atomizer coil. Pod systems, on the other hand, use separate modules (pods) that contain the e-liquid and atomizer.

Are vape mods suitable for beginners?

Typically, vape mods are not recommended for beginners due to their size, cost, and advanced features.

Can I switch between MTL and DTL vaping on a single device?

Some devices have variable wattage and multiple coil sizes, allowing configuration for either MTL or DTL vaping.
